Dye Penetrant Inspection (DPI)

Dye Penetrant Inspection (DPI) is used to detect surface breaking discontinuities such as cracks or porosity in non-absorbent materials i.e. steel, aluminium, composites etc.

At PTS we have a number of PCN level II engineers capable of carrying out DPI either on site or in our laboratory using our bespoke dye penetrant inspection facilities. We also have PCN level III engineers able to produce bespoke inspection procedures specifically tailored to customer needs when required.

PTS is highly experienced in all techniques of Dye Penetrant Inspection including fluorescent and colour contract methods. Inspection can be carried out either in a workshop, on in service items at sites around the country or at our purpose built laboratory in the Midlands.
